Title: Improvements in or relating to cameras
IPC: G03B17/53
Filed: 1928-10-16
Abstract: 324,096. Graseby, R. C. Oct. 16, 1928. Automatic and coin - freed apparatus. - An automatic camera for taking a series of photographs on a sensitized strip comprises (1) a, motor-driven horizontal shaft having at one end means to operate a shutter, (2) a vertical spindle geared to the shaft towards one end and adapted to move the sensitized strip in a step-by-step manner, and (3) a second vertical spindle geared to the shaft at an intermediate point and adapted to drive means for severing the exposed strip. When coin-freed, the apparatus includes a coincontrolled balanced lever for starting the motor. In one form, Fig. 1, the horizontal shaft 10 driven by the motor 8 carries at one end a cam 91 which operates a shutter of the type described in Specification 324,072. Sensitized material from the spool 110 is drawn across the lens aperture 112 by the toothed drum 25 carried by the vertical spindle 13 which is moved once in every revolution of the shaft 10 by the engagement of a cam on the shaft with a series of pins' on a wheel fixed to the spindle 13. After a series of photographs have been taken, the strip is severed by a knife 54 actuated through levers 52 and 49 by a cam 33 on a spring drum 30 operated as described in Specification 324,091, [Class 31 (i), Cutting and severing machines &c.]. This device is driven by the spindle 11 which is geared to the shaft 10. Coin-freed mechanism 62 as described in Specification 324,073, [Class 27, Coin-freed apparatus &c.], is used to control the operation of the motor. The spindles 11 and 13, or a separate spindle driven by the shaft 10, may operate contacts of an indicator between exposures. The spindle 11 also carries a cam adapted to switch on the lights. The apparatus is enclosed in a fire-proof box 1 having shutters, held open by fusible members &c., over the coinaperture and lens aperture as described in Specification 324,092.

Abstract: 714,581. Knitting. LOMBARDI, V. Dec. 7, 1950 [Jan. 13,1950], No. 30013/50. Class 74 (2) In a knitted fabric are arranged in a predetermined pattern, a plurality of bulges, each formed by the provision of a greater number of courses between two spaced courses in certain interior portions of the fabric than between the said two courses in other parts of the fabric, the coursewise ends of at least certain of the excess courses being tied into the fabric. The body yarn may be constituted by yarns 10, 11, 12 fed by wrap feeders fed back and forth across sections C, D, E of the fabric, wrap yarns 14, 15, 16 being knitted in to form a bulge and help to tie the sections together: Fig. 2 shows an article embodying such fabric and used in the formation of a hat, that part containing the: yarns 14, 15, 16 gathering into a U-shaped bulge 33 which will form the hat brim. Fig. 5 shows a fabric having a multiplicity of bulges and formed from main yarn 62 and wrap yarns 63-66. The extra courses may be interspersed in large groups. Fig. 9 shows a fabric in which courses 91, 92, 104 and 105 extend for the full extent of a wrap yarn feed, courses 93 and 103 run from one end of the bulge to the opposite end of the portion of fabric, courses 94-98 are of gradually decreasing extent and courses 98-102 are of gradually increasing extent. Other variations are described. The bulges of the ground yarn may be in differing colours. A fabric may be composed entirely of wrap yarns and embody bulges in design formation within other design portions, as in Fig. 19: the dotted lines indicate yarns caught into the fabric without knitting.

Filed: 1954-10-19
Abstract: 762,550. Cathode-ray tubes. MORLE, C. W. [Philco Corporation]. Oct. 19, 1954, No. 30049/54. Class 39(1). A cathode ray tube, preferably a colour television receiver, has a gun for producing two or more electron beams individually controllable in intensity comprising conductive flanged cylinder 20, Fig. 2, housing cathode 30 and having peripheral apertures through which intensity control electrodes 34, 36 pass, electrodes 34, 36 being coplanar and having insulating spacing washers 44, 46 on either side thereof, and the emissive cathode surface is positioned closely adjacent to the intensity control electrodes 34, 36. A flanged cylinder 20 of nickel or stainless steel has slots 26, 28 through which spade shaped control electrodes 34, 36 pass. The control electrodes have apertures 38, 40 of equal or unequal sizes according as to whether the beams passing through them are of equal or unequal cross section, and are held in position by insulating washers 44, 46 preferably of mica or ceramic and a flanged metal ring 48 welded to cylinder 20. It is stated that electrons cannot pass through the gap between the two control electrodes. The indirectly heated cathode 30 is carried by steatite or lavite disc 50 and is spaced from the control electrodes by annular steatite or lavite spacer 56 ; disc 50 is locked in position by flanged ring 58 welded to 20. All the spacers are accurately dimensioned. The assembly is supported by ears 68 fused to glass rods and by the electrode leads ; the glass rods also carry the gun anode. A ribbed disc, Fig. 1 (not shown) centres the assembly within the tube neck. To make both beams coincide where they strike the screen, the shape of the control electrodes is modified by giving the adjacent ends of the control electrodes semi-spherical shapes or by inclining their ends, Figs. 4, 5 (not shown). The invention is preferably applied to the dual beam colour television receiver disclosed in Specification 745,353 employing indexing means in which the intensity of the auxiliary beam is independently varied by a pilot carrier signal having a frequency outside the frequency bands of the colour video signals to generate an indexing signal. It may also be applied to colour television receivers in which each beam carries a video signal of one colour.

Diagonally-disposed pairs of lap joints are secured and tied together by pins m, distance tubes l, and nuts n with hemispherical inner ends. A simpler form of frame member is described consisting of a pair of boom strips and a pair of web strips united by a single pair of diagonal shouldered rivets. In a modification, a lower portion consisting of side pieces g, j, Fig. 3, and a boom k is added to such a frame member, the lower pair of joints being secured by a horizontal shouldered rivet p.

Filed: 1964-07-29
Abstract: 1,056,615. Door operating mechanisms; doorchecks. RONAN & KUNZL, Inc. July 29, 1964 No. 30159/64. Heading E2M. A power operated door opener fitting within a thin header or threshold chamber and operated for example by a mat switch comprises a hydraulic piston 48 and cylinder 22 which move a cam plate 34 having a slot 37 engaging a roller 40 mounted between superposed crank arms 39, the door pivoting about the crank 29. Springs 23 are compressed when the door is opened and assist the closing action. A supply conduit 16 and return conduit 17 connect the cylinder to a pump. In the open position the crank 29 abuts a stop 45 having an aperture 46 to form a resilient abutment. Initial opening of the door is rapid and an adjustable needle valve (75 Fig. 8, not shown) determines the final speed of opening. Pressure is maintained to hold the door open against the stop 45. When the door closes, oil in the inner end (the right hand end in Fig. 3) of the cylinder 22 escapes through a hollow needle valve 96 slidable in a bore against the pressure of a spring. Further valve means ensures that the closing movement is checked. (Valve 104 Fig. 16 not shown constitutes a door closing speed control valve). The springs 23 finally give a positive closing motion, for emergency operation, the door may be pushed open in the opposite direction when the roller 40 presses on a nose portion 38 of the cam plate 34 and moves the plate slightly to the right in Fig. 3 the arm 39 is then free to swing the roller in the cam opening 35. An inclined edge 120 on the cam plate 34 presses against the roller 40 in the door closed position to prevent rattle or opening due to wind pressure. The device may be applied to multiple doors.
